OVERVIEW
QUALITY THAT LASTS!
ACTIVE INTENSIVE SEEDBED PREPARATION
Kverneland power harrows have a a self-supporting gearcase, therefore a heavy frame is not necessary. The power harrows are a successful and tested construction principle for heavy duty operations. The advantages are compelling: High stability for the whole working width, the rotor drive is isolated from distortion or bending stresses. All mechanical stresses are transferred directly on to the shock absorbing headstock.
One concept - That fits together!

Self-supporting gearcase Strong resistance to abrasion and torsion is one of the main characteristics of the double bending gearcase in sandwich design. The "laminated bottom” and the wide, wear- resistant gear profile ensure reliable heavy- duty use. The tapered bearings have a high basic load rating which offers increased security and reliability, giving an extended working life. Tine holder & Tine First priority is durability and protection against stones and good access. The rotor shaft and tine holder consist of two parts for easy maintenance and long-lifetime, even in stony conditions. Very important – the tines are easy to change due to the Quick-Fit system. The two large bearings are very strong and the
Rotor clearance Four rotors (8 tines) per metre ensures coverage of the entire working width. This represents an optimum number for thorough crumbling of the soil. Minimal torque on drive gears means minimal wear. Robust headstock The headstock is very strong due to the use of thick-walled steel offering several possibilities for combining with mounted and semi-mounted seed drills. The length thus optimising weight transfer. Roller The final step of perfect seedbed preparation is consolidation. A weatherproof finish allows moisture retention when dry and transition (water infiltration) through the profile in wet conditions.
large distance between the bearings ensure maximum resistance to radial stress, even in the most extreme conditions. The forged boron steel tines prepare the seedbed by cutting, crumbling and levelling the ground. The tines are extremely hard wearing and fracture- resistant. The outer tines turn inwards, which together with the side deflectors avoid ridge formation. An important characteristic is the helical tine positioning which minimises the risk of damage (from stones) and ensures a more homogeneous and even load on the gearcase. In addition, this special design also reduces the amount of wet soil brought to the surface (especially important in the spring time); the moisture stays next to the seed for improved germination.
